  • Kernel smoothing on tag counts

    Hi all!
    I'm quite new with the analysis of ChIP-seq and RNA-seq data, and I just started a new project on the analysis of different kind of ENCODE data.
    Breifly, my problem is that I have to process multiple alignment files from different ChIP-seq assay (I meant different histone mod.) and convert them into normalized genome-wide signal coverage tracks, similar to the work performed in
    ENCODE-wiggler.
    Now I have to perform the analysis by my own with some modifications. I have for each ChIP-seq experiment wig files with coverage information (read counts) for each single position. I just wanted to use these files as input to generate density profile using kernel smoothing. Do you think is possibile to use the KernSmooth R package? I thought that this is exactly what I need but the function obviously compute density profile of data values in x, whilst I want to use it on values (tag counts) that are fixed along the chromosomic coordinate.
    Any suggestion? Is there maybe another package/function more suitable for this case? thanks a lot in advance.

    The Impact of AI in Genomic Medicine
    by seqadmin



    Artificial intelligence (AI) has evolved from a futuristic vision to a mainstream technology, highlighted by the introduction of tools like OpenAI's ChatGPT and Google's Gemini. In recent years, AI has become increasingly integrated into the field of genomics. This integration has enabled new scientific discoveries while simultaneously raising important ethical questions1. Interviews with two researchers at the center of this intersection provide insightful perspectives into...

    Multiomics Techniques Advancing Disease Research
    by seqadmin


    New and advanced multiomics tools and technologies have opened new avenues of research and markedly enhanced various disciplines such as disease research and precision medicine1. The practice of merging diverse data from various ‘omes increasingly provides a more holistic understanding of biological systems. As Maddison Masaeli, Co-Founder and CEO at Deepcell, aptly noted, “You can't explain biology in its complex form with one modality.”

    A major leap in the field has
